MQ-2 Gas Sensor Module for Detecting Combustible and Harmful Gases in Arduino and DIY Electronics Projects

Description:
The MQ-2 Gas Sensor Module is a versatile and highly sensitive sensor capable of detecting a wide range of gases, including LPG, methane, hydrogen, propane, alcohol, and smoke. It is widely used in Arduino projects and DIY electrical circuits for gas leakage detection, air quality monitoring, and safety systems. With a simple analog and digital output, it is easy to integrate into microcontroller-based systems.

Specifications

Key Features:

• Wide Detection Range: Capable of sensing a variety of combustible and harmful gases.
• Dual Output: Provides both analog and digital signals for flexible integration.
• High Sensitivity: Quickly responds to gas concentration changes.
• Adjustable Sensitivity: Fine-tune detection levels using the onboard potentiometer.
• Compact and Durable: Fits easily into small projects and offers reliable performance.
•  

Applications:

• Gas leakage detection in homes and industrial setups.
• Air quality monitoring in IoT and smart devices.
